jsonp

If you are working with a javascript page, and need a JSON callback mechanism, you can do it.
You just need to provide an additional callback variable. This callback is usually handled via the javascript library, but here is an example.

This would automatically call the JavaScript function jsonp1192244621103 with the parameter set to the results of the RPC call.

Limitations

HTTP GET requests are limited to URI of 8190 bytes maximum length. However, the official AUR instance running on a nginx server with HTTP/2 uses the default URI maximum length limit of 4443 bytes. Info requests with more than about 200 packages as an argument will need to be split.
